Common settings you will need to apply to get your Outlook working correctly for most of our normal hosting environments:
Open Tools-->Accounts
Your settings should be:
POP3: mail.yourdomainname.com
SMTP: mail.yourdomainname.com
User Name: joe@yourdomainame.com (Your full email address)
PW: (Your Password Here)
If your Sending fails it may be because you are using Charter Cable or another provider that blocks you from sending email through their port. To get around this:
ACCOUNT SETTINGS:
Click "More Settings--->Outgoing Server" check "My outging server (SMTP) requires authentication" AND "Use Same Settings as my incoming server"
Advanced Tab: Your standard SMTP outgoing port is 25. If you are using AT&T or Charter they may already be using or blocking that port. If that is the case, by pass it by changing your port settings: Change the Outgoing server (SMTP) to 825 (shared server) or 2525 (dedicated server)
Click OK and test things.
